BV IMR 2500MAH 18650 Battery

What Is An LMR 18650 Battery?

The batteries used in almost all vape devices are of 18650 Li-ion type. They are available in varying capacities but all work in the same way in so much that 18650 batteries consist of three parts:

The anode: Most lithium-ion cells use graphite or hard carbon as the negative electrode host material
The electrolyte:  Soluble salts, acids or other bases in liquid, gelled and dry formats
The cathode: The selection of the positive electrode material is much more varied. For our purposes, the IMR battery used in vape devices uses lithium and manganese =  LiMn2O4 (also called LMO)

Many of the high-drain batteries used in vaping have IMR chemistry because manganese is awesome. It allows your battery to discharge at a high current while maintaining low temperatures. This means that it’s safer than other types of battery.

We could talk about electrochemistry and the relative electron energies of the anode, electrolyte, and cathode of a thermodynamically stable redox pair in a Lithium-ion Battery but we won’t, here is the simple version. 

When you push the power switch or inhale on your vape device, you’re giving the green light to chemical reactions inside the battery. As the current starts flowing, the cells inside the battery begin to transform themselves and the chemicals inside their components begin to rearrange themselves. Inside each cell, chemical reactions take place involving the two electrodes and the electrolyte that separates them. This reaction causes electrons (the tiny particles inside atoms that carry electricity) to pump around the circuit the battery is connected to, providing power to your device. The cells in your battery contain only limited supplies of chemicals so the reactions cannot continue indefinitely. Once the chemicals are depleted, the reactions stop and you need to recharge.
